the earphone of Samsung are very well made, battery lasts very long, the sound is absolutely in Ordnung.das link to my S5 was a no-brainer, but since the last update was nothing more, they unfortunately had to return, too bad the product gets from me the entire score, it had to update datellos funktioniert.TOP.Samsung has something going on zuholen, also in terms of Bluetooth only 3.0 garnichtmehr, mind.4.0 or even 4.1 and it would be nice with APTX.
